Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

Course Title: Criminal Investigation Unit Number: Unit 3 2. What are the similarities and differences between an arson investigation and a bombing investigation? Arson is the intentionally setting of fires to property‚ persons‚ and vehicles. Bombing can be defined as the offense of using a projectile‚ or explosive weapon to cause alarm‚ panic‚ danger‚ or death. There are many similarities and differences between the investigation of a bombing and the investigation of arson. The similarities

determine whether or not a chemical reaction occurred after the mixing of various chemicals. The evolution of a gas‚ the formation of precipitation‚ and the change of temperature or color are all indicative of a chemical reaction. It was assumed that a reaction did not take place if the mixture of chemicals exhibited none of these characteristics. Several precipitation‚ complex-ion formation‚ redox‚ and acid-base reactions were performed. Redox: Decomposition Reactions In a 13 x 100 mm test tube‚ 2 mL

Hypothesis - The idea I aim to test in this experiment is the relationship between the mass of magnesium and mass of oxygen once the magnesium has been heated and reacted with the oxygen. There will be 3 variables in this experiment. The independent variable will be the mass of magnesium ribbon as different measurements will be taken and used for each trial. The dependant variable will be the mass of Magnesium Oxide‚ this is a measured variable as the mass of oxygen can be calculated and will enable

energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy‚ and a phase may change‚ such as in melting and boiling. Thermochemistry focuses on these energy changes‚ particularly on the system ’s energy exchange with its surroundings. In combination with entropy determinations‚ it is used to predict whether a reaction is spontaneous or non-spontaneous‚ favourable or unfavourable. Chemical reactions can be divided into two based on the

George VI became King unexpectedly following the abdication of his brother‚ King Edward VIII‚ in 1936. A conscientious and dedicated man‚ he worked hard to adapt to the role into which he was suddenly thrown. Reserved by nature‚ and of deep religious belief‚ he was helped in his work by his wife.

Analysis of Winston Churchill’s Eulogy for King George VI In Winston Churchill’s Eulogy for King George VI‚ he does an outstanding job of honoring the former king with respect and true sadness that a great friend and king had passed. While still addressing the grief everyone was experiencing from the loss of such a beloved and righteous king‚ he ends the speech with an optimistic air‚ respectively giving his best hopes and allegiance to the new queen. The eulogy uses ethos and pathos throughout
